A non-coherent SAC-OCDMA system using extended quadratic congruence codes for two-code keying scheme in passive optical networks
چکیده انگلیسی

In this paper, we propose a family of extended quadratic congruence codes for two-code keying (TCK) with the corresponding encoding/decoding architecture for passive optical networks (PONs) in spectral amplitude coding optical code division multiple access (OCDMA) systems. The proposed system can simultaneously eliminate multi-user interference (MUI) and further suppress phase-induced intensity noise (PIIN). We reduce the complexity of the encoding/decoding architecture of the optical line terminal reduced by exploiting arrayed waveguide gratings (AWGs) and the properties of the extended quadratic congruence codes (EQC codes). Moreover, we also design a deployment method to increase the number of simultaneous users. Our numerical results demonstrate that the proposed system outperforms the improved quadratic congruence codes (improved QC codes).


► We have proposed a set of EQC codes for two code keying.
► The OLT transceiver structure takes shape in EQC codes for two-code keying.
► The deployment method increases the number of simultaneous users significantly.
